IMPROVEMENT IN EXTRAC'IIN'G TURPEHII NE FROM PINE-TREES.

The Schedule referred to in these Letters Patent and making pan: of thesame 'the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of an external view of apine-tree, with an incision therein formed upon my .plan', and my,gathering-apparatus attached.

Figure 2 is a sectional view, and

Figure 3 is a detail.

My invention has relation. to means for extracting and gatheringturpentine from pine-trees; and

It consists in anovel method of tapping such trees,

and an improved apparatus for securing the turpen-' tine.

A of the drawings represents theincision cut in the tree, the lower sideor base of which is formed with a saw, and the upper side usually withan axe.

The lines a. a show the lower side of the incision, and the lines o cthe upper side. The space between these several lines is cleared with achisel, which removes the chip. The letter B represents a gash cutacross the tree, at rightangles therewith, for-the purpose of holdingthe spout 0-, next mentioned.

'0 is a spout or conduit for the turpentine. lt'is usually constructedof tin, with its upper end cut and bent, as shown in fig. 3, and adaptednct only to sit firmly in the gash B, but also to conduct the turpentinedownward to the bucket D, and serve as a sup pOrtand stay for saidbucket.

The letter D represents my bucket, which, when on duty, is held in placeby the joint support of the spout O and the nails 11. The latter consistof two twentypenny nails driven firmly into the tree at such dis tancefrom the gashB as will allow the spout to serve as a stay and supportfor the upper end of the bucket, while they (the nails) support itsbottom, as shown on tigs'land 2..

.I find by experiment that for extracting turpentine from the tree, theuse of a saw is preferable to an axe, inasmuch as the blows of thelatter tend to close the pores of the timber, and prevent, to someextent, a rapid flow of the liquid.

The gashes cut by the saw below the main incision.

should be closed by a mortar of gypsum, or other suitable material, toprevent waste.
